EMMET B. RAYMOND, OF DALLAS, TEXAS, ASSIGNOR TO RAYMOND OIL BURNER COMPANY, A PRIVATE CORPORATION OF NEW JERSEY.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent N o. 742,064, dated October 20, 1903.

Y Application filed October 28, 1902. Serial No. 129,123. (No model.)

This invention 4relates to a burner which" maybe used either with crude or refined oils, and the burner is adapted particularly to be applied to the fire-boxes of stoves.

It comprises certain novel features of con. struction which will be fully pointed outY by the flange a3.

hereinafter. v

This specification is an ex'actdescription of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure l is a vertical section of the invention, and Fig. 2 is a section on the line 2 2of Fig. 1.

The base d has a downwardly-extending iiange a', adapted to rest on a support and f a pan in which the oil is ignited.

Supported on the base a, by legs c is the preferably cylindrical body @,and in this body are arranged ribs c, on which the frusto-conical mixer d is loosely placed, this mixer tapering toward its upper end and having said end commensurate with the top of the body c. Supported by legs c' on top of the body c'is a cap e, the under side e2 of which is of conical form, producing a deiiector for the burning gases. Y

The oil-supply pipe b passes within a nipple a4 in the center of the base a, and from this nipple a4 a vertically-disposed supply-pipe f extends. This pipe is open at its inner end and has a cone g screwed or otherwise fastened thereto. This cone has a series of annular cups g formed thereon, said cu ps gradually increasing in capacity from the top 5o downward, and on the bottom of the cone are formed a number of downwardly-projecting The base a alsoV 1 llugs g2, which are employed in case the cone i lis screwed onto the pipe f, these lugs facilitating the engagement of a suitable instrument with the cone to screw or unscrew the same.

Y In the use ofthe burner it is placed Within `the-lire-box of the stove on the grate thereof, and the air-feed is forced to pass into the bot- .tom of the body c and through the conical 'mixer d. The valvev (not shown) of the sup ,ply-pipe is then opened and the oil is allowed to flow from the top of the pipef through the vcups gf of the cone g and into the pan' formed When this has been done, the oil in the pan should be ignited and the llame thereof will heat thoroughly all of the `parts of the burner and the llame will be communicated tothe oil in the cups g'. After the oil in the pan as has been consumed the flow through the pipe f'should be'regulated so that the oil will be burned before it overflows from the lowermost cup g', or, in other words, when the apparatus is normally at work there is no burning oil in the pan d3. The mixer d forces. the air inward toward the burning oil, and the cap e, with its detlector-like surface e2, becomF ing highly heated by the flame will increase the combustion of the burning gases, so that such combustion will be complete and no smoke will be developed by the burner.

Various changes in the form, proportions, .and Aminor details of my invention may be resorted to at Will Without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, I l

1 claim as new and desire to secure by Letters Patent- 1. An oil-burner, consisting of a base provided with a downwardly-projecting flange having openings, an upwardly -projecting ilange forming a cup, and a central nipple with which an oil-supply pipeis adapted to be connected, a cylindrical body supported by legs on the base and provided with internal ribs, a hollow cone having a series of ex- -terior annular cups, a tube, to the upper end of which the cone is removably secured, said tube extending downwardly through the cone and secured to the nipple of the base, a conical mixer supported upon the ribs of the body and into which the cone extends with its upper end terminating short of the top of the mixer, and a cap having a conical lower face and provided with legs resting upon the upper edge of the body, as set forth.

2. An oil-burner, comprising a base provided with apan on its upper face and with a central nipple with which an oil-supply pipe is adapted to be connected, a cylindrical body supported by legs upon the base, a hollow cone having a series of exterior annular cups, a tube to the upper end of which the cone is removably secured, said tube extending downward through the cone and secured to the nipple of the base, a conical mixer supported in the said body and into which the cone extends with its upper end terminating short of the top of the mixer, and a cap having a conical lower face and provided with legs resting upon the upper end of the said body, as set forth.

3. An oil-burner, comprising a pan, an oilsupply pipe leading through the bottom of the pan and projecting upwardly therefrom, a hollow cone having a series of exterior annular cups and secured at its upper end to the upper end ot the supply-pipe, a cylindrical body supported by legs on the pan, a conical mixer in the body and into which the cone extends with its upper end terminating short of the top of the mixer, and a cap having a conical lower face and provided with legs resting upon the upper end of the said body, as set forth.

4. An oil-burner, comprising a pau, a cylindrical body of less diameter than the pan and supported above the bottom thereof by legs, a tube projecting centrally upward from the bottom of the pan and with which a supply-pipe is adapted to be connected, a hollow cone having a series of exterior annular cups, said tube extending up through the cone and tothe upper end of which the cone is detach-` secured to the upper end of the said tube, a'

removable mixer within the body and into which the cone extends, and a removable cap supported on the upperend of the body, said cap being of greater diameter than the body,l

as set forth.

6. An oil-burner, comprising a pan, a cylindrical body of less diameter than the pan and supported above the bottom of the same, a tube projecting upward from the bottom of the pan and with the lower end of whicl1,be low the bottom of the pan, a supply-pipe is adapted to be connected, a cone on the upper end of the tube and having exterior annular cups, a mixer within the body and into which the cone extends, and a cap supported on the upper end of the body, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
